Do I Need A Heater For
My Goldfish Aquarium?

Most aquarium owners wonder if they need an
aquarium heater for their goldfish tank. The answer to many
people's question, "Do I Need a Heater For My Goldfish
Aquarium?", is goldfish are a coldwater fish and require no
need of an aquarium heater installed. Goldfish are very hardy
and are not that vulnerable to sudden changes in temperature
like tropical fish are. Sudden quick temperature changes in
aquariums that have tropical fish will most likely kill your
fish or cause sickness and disease to occur. Your goldfish on
the other hand will be just fine as the water in your tank will
be at room temperature. To further answer your question is that
goldfish in ponds hibernate overwinter in extremely coldwater so
if they can survive no problem outside they will do just fine in
your aquarium at home with no heater installed on your fish
tank.
